Presentation transcript:

Experimental Research Definition: Efforts to gain control over the variables of interest and establish if-then causal relationships. Involves random assignment and manipulation. (dependent vs. independent variables) Disadvantages: 1) artificial and limited in relevance 2) relations among isolated variables may not hold 3) temporally limited 4) demand characteristics Advantages: 1) potential for careful manipulation of the variables of interest 2) data free from biased or subjective interpretation 3) establishment of cause and effect relations

Experimental Research Seligman’s Theory of Learned Helplessness Exposed dogs to unavoidable shock or not Place dogs in new situation where shock is avoidable Dogs who were initially exposed to inescapable shock are less likely to escape from shock in new situation Concluded that dogs “learned” they were helpless. Offered that this might serve as model of human depression.

Experimental Research around Personality Think of a question that interests you about personality: Could this question be addressed using an experimental method? Explain. If so, describe a design you might use. If not, describe an alternative design.
